190 BOTANY. 



as great as the width. E. Australis from Australia, as well as Cicendia 

 from Europe, have stigmas like the American species, but E. Chilensis (at 

 least a specimen collected by Ochsenius in Valdivia, which I refer to that 

 species) differs from all the others in having elongated, cuneate, emarginate 

 stigmas. 



The seeds of Erythrcea are identical with those of a large group of 

 Oentianece, which comprise perhaps all of Grrisebach's Chironiece and Chlo- 

 rece, being very numerous and very small, from | to scarcely more than 

 J mm in the longer diameter, and, when fully mature, globose or oval, with 

 their surface favose-reticulate. 



The North American genera belonging to this group may be arranged 

 thus : 



1. Stamens inserted in the tube : Eeythe^a. Eustoma. 



2. Stamens inserted in the throat : Sabbatia. Miceocala. 

 Chloea, Chieonia, and Seb2ga of the Old World also belong here. 

 My investigations have convinced me that the genus Cicendia, or at 



least its typical and original species, C. pusilla, is nothing but a reduced 

 form of Erythrcea, distinguished from it only by its small oval anthers, less 

 than 0.5 mm in length, too short to twist much, but still, when drying, some- 

 times twisting a little. Its stigma is by no means capitate, but regularly 

 bi-lamellate, and, much like that of the American species, triangular-flabel- 

 late, and broader than long. The flowers are 4-parted, which often occurs 

 in genuine species of Erythrcea; seeds 0.4 mm long, large for the size of the 

 plant. It will have to bear the name Erythraa pusilla. 



Erythema Douglasii, Gray, Fl. Calif. 1, 480; Syn. 113. — Slender, 

 a span to a foot high, loosely and paniculately branched, usually sparse- 

 flowered ; leaves from oblong to linear, acutish ; flowers on strict, slender 

 pedicels, 4-5" wide ; lobes of the pale pink corolla obtuse, much shorter 

 than the tube ; anthers usually only l mm long, style short, stigma about 

 l mm wide ; seeds sub-globose, 0.4 mm in diameter. — Arizona, Utah, and 

 northwestward to Oregon. This plant has been confounded by Mr. Watson 

 with his E. Nuttallii, which, however, is a smaller and more leafy plant, 

 with larger flowers and much larger seeds (0.65 mm long), but much smaller 

 stigmas.
